The blackout began around 9:30 p.m. EET on Oct. 20 when the attack hit critical energy facilities in Chernihiv Oblast, plunging the northern part of the region into darkness.
Emergency crews are working to restore power to hospitals, kindergartens, and critical infrastructure first, but authorities said there is no timeline yet for full restoration.
Backup power sources are keeping heat and water systems partially operational. Chernihivvodokanal, the municipal water company, reported that pumping and drainage stations are functioning from alternative energy sources. Water is being supplied to the first several floors of residential buildings, reaching up to the sixth floor in some areas.
Public transportation remains disrupted, with trolleybus routes suspended due to the power outage. The city has opened 22 emergency centers where residents can warm up, charge devices, and access hot water.
The attack is part of Russia's escalating campaign to cripple Ukraine’s energy grid to disrupt heating and power supplies as the country braces for the winter months.
